B-Line B24SH-240SS6 Eaton series strut channel, 1.62" channel height, 240" channel length, 1.62" channel width, Steel, 14 Gauge, SH hole pattern, B24 channel type, Stainless steel type 316

That is exactly what the 316 stainless version is for. The B24SH-240SS6 is furnished in stainless steel type 316, the alloy specified where chloride exposure is the problem: marine and coastal air, food and beverage wash-down bays, water and wastewater treatment, and chemical process areas. For a dry indoor electrical room, plain or pre-galvanized strut does the same mechanical job for less material cost.

Yes. The channel opening is the standard 1-5/8 inch profile (1.62 inches across), so spring nuts, channel nuts, pipe clamps, brackets and end caps made for 1-5/8 strut drop right in. One caution on a 316 job: pair it with stainless hardware. Putting plated carbon steel nuts and bolts in stainless strut in a corrosive environment defeats the reason you bought 316.

The B24 channel carries the SH hole pattern, which is B-Line's short-slot punching in the back of the channel rather than a solid back. That lets you bolt the strut directly to structure through the back at regular intervals without field drilling. If you need an unpunched back for a continuous weld or a clean run, SH is not the pattern to order.

The manufacturer part number is B24SH-240SS6. Reading it out: B24 channel type, SH hole pattern, 240 inch length, SS6 for stainless steel type 316. Give that number to a distributor and you'll get the right stick.

It ships as a single 240 inch stick and is cut to length in the field like any strut, with a bandsaw or abrasive chop saw. Two things to plan for with 316 stainless: use a blade and any grinding media reserved for stainless so you don't embed carbon steel particles in the cut face, and expect a 26.8 lb piece that takes two people to handle at full length.
